Vehicle data recording
This model’s ECU stores certain vehi-
cle data to assist in the diagnosis of
malfunctions and for research and de-
velopment purposes. This data will be
uploaded only when a special Yamaha
diagnostic tool is attached to the vehi-
cle, such as when maintenance checks
or service procedures are performed.
Although the sensors and recorded
data will vary by model, the main data
points are:
Vehicle status and engine perfor-
mance data
Fuel-injection and emission-relat-
ed data
Yamaha will not disclose this data to a
third party except:
With the consent of the vehicle
owner
Where obligated by law
For use by Yamaha in litigation
For general Yamaha-conducted
research purposes when the data
is not related to an individual vehi-
cle nor owner
